    Brunelleschi's Dome

    • 1007 Words
    • 5 Pages

    Maria del Fiore Cathedral in Florence also named as a Brunelleschi`s dome. Brunelleschi`s Dome was built as a pride of European construction to attract people from other parts of the world. According to Brown, D. (2016), Brunelleschi`s structure has a double shell, which is supported by sturdy pillars to prevent problems caused by its size. The inside shell was made from light materials such as volcanic rocks and the outside shell was made from wind and rain resistant material. According to Brown, D. (2016), all the architectural elements make the dome stable without any supporting structures. According to Mueller, T. (2014, February), since this cathedral is very big and its weight is tens of thousands of tons, it will have some damage at the lower level of the foundation and walls because of pressure. To reduce the weight, Opera del Duomo was built with volcanic rock. The dome was built from the ground up to 46 feet using stone, and then lighter materials were used. Based on my knowledge and experience, stone and concrete are very high-density materials compared to volcanic rock, although stone and concrete can withstand heavy loads without damages. That is the reason why currently there are so many skyscrapers made of concrete. A different set of designing engineering objectives is designing bridges. A majority of bridges were built mostly as a strategic construction that connects two sides of a river so people can quickly cross it. The first bridges had been…

    Adakite Research Paper

    • 868 Words
    • 4 Pages

    Introduction Adakites are volcanic rocks that are diagnostic of high temperature, high pressure conditions, (Stevenson, 2005). Their composition ranges from felsic to intermediate, and are characterized by assemblages of plagioclase, and often amphibole, and are identified by their unique geochemical signatures. Adakite is named Adak Island, Alaska, where it was first documented,(Defant and Drummond, 1990). They are often formed through the partial melting of a young subducting slab of…

    2.4. Hydrocarbon potential Previous work reveals presence of mature sedimentary sequence was derived from Jurassic to lower cretaceous periods in the north part of Lake Malawi which has hydrocarbon reservoir prospects. Existence of thick sedimentary sequence rock could possibly trap hydrocarbon especially in lower Shire valley, northern of Lake Malawi. Presence of large proportion volcanic clasts interbedded with sedimentary rocks transported by rivers present for extensive alluvial plain…

    Tapo Volcanic Zone Essay

    • 1086 Words
    • 5 Pages

    Taupo Volcanic Zone The Taupo Volcanic Zone is a highly active volcanic region situated in the central part of the North Island in New Zealand. The Taupo Volcanic Zone (TVZ) stretches from Ohakune in the south of the Bay of Plenty to White Island in the north. It is estimated that the Earth’s crust below the Taupo Volcanic Zone may possibly be as small as 16 kilometers think and currently moves approximately 8mm per year. The TVZ is named after Lake Taupo, the caldera of the formaly largest…

    • 2 Pages

    The location I chose for this assignment is my home county, San Diego. San Diego is known for having the best weather in the United States, which it can attribute to its geology. San Diego is also well known for consistent droughts; however, its current unique geography is a result of ancient rivers and seas depositing Cretaceous and Tertiary sedimentary rocks. As a result of these ancient rivers, “San Diego County can be divided between three distinct geomorphic regions: the Coastal Plain…

    tempertures. Proof of this is in the Colorado Rockies, sediment left behind, mostly large fossils of female ammonites or squid, crabs and other sea creature fossils. Just outside Denver, Colorado lay large 60 degree a ngeled slabs of rock known as the Flatirons. Over millions of years sediment become compressed into these layers of rock. Clues to what may have caused the tilted sedimentary layers are the darker rock at the bottem called granite, which has no layering like the rock on top of…

    In 1965, the serpentine rock became California’s state rock; they are abundant in central and northern California. The serpentine rock is a metamorphic rock that forms by the hydration of rocks from the Earth’s mantle; these types of rocks will rise towards the Earth’s surface along fault zones. It can be found in various colors from dark green and brown, to blue with a glossy surface. However, these rocks tend to be slippery and creates a high risk for land slides. Through a series of…

    billion years ago (oldest) during the Grenville orogeny (Precambrian) which featured sediment deposits and volcanic activity, which marked the creation of the supercontinent Rodinia (Keary, 2009). Following the Grenville orogeny there was a period of erosion which allowed for a smooth surface for more deposition. When Rodina began to break up by the Iapetus ocean opening through rifting, led to volcanism. As the ocean opened it gave the conditions for the limestone and dolomite to form, which…

    sedimentary and (more rarely) volcanic rocks. Two fluids are thought to be involved: an oxidized brine carrying copper as a chloride complex, and a reduced fluid that commonly formed in the presence of anaerobic sulfatereducing bacteria. For a sediment-hosted copper deposit to form, four conditions are required: (1) an oxidized source rock, (2) a brine to mobilize copper, (3) a reduced fluid to precipitate copper, and (4) conditions favorable for fluid mixing (Haynes, 1986a, b; Sverjensky, 1989;…
